[Obstetric damage to the perineum and the anal sphincters. Reconstruction surgery].

Damage to the perineum, vulva, anal sphincters, rectal wall and the fascial structures of the pelvic floor may be caused by obstetric trauma. Emergency surgical treatment aims at control of the bleeding, anatomical reconstruction of the disrupted tissues and minimization of the risk of infection. Suturing of the rectal wall and mucosa of the anal canal is followed by reconstruction of the perineal body internal and external anal sphincters, vulva and the perineum. Delayed surgery is undertaken after the complete healing of the obstetric tear. All cicatricial fibers must be saved to reinforce sphincters and perineal body muscles suturing. Anal levators and perineal transvers muscles suturing is used for the rectovaginal septum and pelvic floor reconstruction. Anal sphincters are reconstructed by the 'overlapping' technique. X en Z suturing is used for a perineal skin plasty.
